TCONRS is an 8-bit readable/writable register that selects 8-bit timer TMRX/TMRY access and

the synchronization signal output signal source and generation method.

TCONRS is initialized to H'00 by a reset and in hardware standby mode.

Bit 7—TMRX/TMRY Access Select (TMRX/Y): The TMRX and TMRY registers can only be

accessed when the HIE bit in SYSCR is cleared to 0. Some of the TMRX registers and the TMRY

registers are assigned to the same memory space addresses (H'FFF0 to H'FFF5), and the TMRX/Y

bit determines which registers are accessed.

Bit 7

TMRX/Y

Description

The TMRX registers are accessed at addresses H'FFF0 to H'FFF5

(Initial value)

The TMRY registers are accessed at addresses H'FFF0 to H'FFF5

Bit 6—Internal Synchronization Signal Select (ISGENE): Selects internal synchronization

signals (IHG, IVG, and CL4 signals) as the signal sources for the IHO, IVO, and CLO signals.
